The Kilpi BORENY-U are mid-calf length socks that are designed not only for cyclists but also for runners or skaters. The knit made of elastane, synthetic fibres and seamless structure is highly elastic, breathable and quick-drying.  The wide elasticated top hem does not pinch or impede blood circulation. A fixation hem around the instep stabilises the position of the sock. Perforated sections on the instep improve micro-ventilation. Available in two stylish colour combinations.
